| 摘 要： | 软磁材料的矫顽力一般分布于零点附近，一方面，在零外加磁场状态下，测量易受到噪声的干扰；另一方面，相对使之达到饱和所施加的最大磁场而言，软磁材料矫顽力的分辨率受到一定的限制。提出一种延迟外推的方法，高精度地估算软磁材料的矫顽力。

| Abstract: | The coercivity of soft magnetic materials is generally near to zero point. On the first hand, in the conditions of near-zero applied field, the results of measurement are often coupled by noise; on the other hand, compared to maximum applied field for saturation magnetization, the resolution of the coercivity of soft magnetic materials becomes low. The paper presents a method of delay extrapolation for high-resolution estimation of the coercivity. |
